Summary: Rayleigh scattering enhanced nanoparticle-doped optical fibers, although restricted in composition and experimental conditions, show potential for distributed sensing applications. In this study, YPO4 nanocrystals are used to develop tunable optical fibers with enhanced scattering and optical performance. The fiber drawing process plays a crucial role in determining the nanocrystal features, and fibers drawn below 1950°C exhibit homogeneous characteristics and performance. The fabricated fibers demonstrate tunable backscattering and optical losses, enabling sensing lengths from 0.3 m to over 58 m. This work suggests a promising future for YPO4 nanocrystals in distributed sensing and opens the door to the incorporation of other REPO4 nanocrystals.

Summary: In this study, the phenomenon of soliton self-frequency shift in a chalcogenide microstructured fiber pumped by a femtosecond pulse was investigated numerically. By optimizing the structural parameters, far-separated zero-dispersion wavelengths with low confinement loss were obtained. A femtosecond tunable soliton with a frequency shifted up to 3.7 mu m was achieved from a 10-cm long fiber, consuming a pump pulse energy of no more than 200 pJ at 2.8 mu m. Our work provides an effective way to construct compact, all-fiber femtosecond tunable mid-infrared laser sources with low operation power.

Summary: In this study, trivalent lanthanide doped Sr2LaNbO6 (SLNO) phosphors were used as novel upconversion luminescence (UCL) materials for UCL and optical temperature sensing. Under 980 nm excitation, Er3+ single doped SLNO phosphors showed bright high-purity green emission. Co-doping with Ho3+ ions significantly increased the red emission from Er3+ ions and enhanced the luminescent intensity. The SLNO:Er3+/Ho3+ phosphor achieved high-purity trichromatic UCL and mixed white light output, and its temperature sensing performance based on the fluorescence intensity ratio was studied for the first time. The Ln3+ doped SLNO UCL phosphors have potential applications in non-contact temperature sensors, full-color displays, and anti-counterfeiting.

Summary: A built-in electric field (BIEF)-driven strategy was proposed for sustainable generation of hydroxyl radicals ((OH)-O-center dot) for long-lasting chemodynamic therapy. A novel Fe@Fe3O4-Cu2O heterogeneous catalyst was designed, allowing continuous Fenton-like reactions and (OH)-O-center dot release for over 18 hours. The sustained (OH)-O-center dot levels led to persistent activation of extracellular regulated protein kinases (ERK) signal and irreversible oxidative damage, resulting in tumor apoptosis. This strategy provides ideas for developing long-acting nanoplatforms for various applications.

Summary: In this study, a novel strip-based lateral flow assay (LFA) using lanthanide-doped upconversion nanoparticles conjugated to antibodies was developed for detecting preeclampsia. The CD44/FKBPL ratio was found to be reduced in early-onset preeclampsia (EOPE) with good diagnostic potential. The improved LFA prototypes achieved a lower limit of detection for FKBPL and CD44, making it more sensitive than the standard ELISA method. The LFA showed promise as a rapid and highly sensitive point-of-care test for preeclampsia, with a 100% positive predictive value and 91% negative predictive value using clinical samples.

Summary: This paper presents a detailed method that utilizes flow cytometry for quantitatively characterizing the performance of continuous-flow microfluidic devices designed for particle separation. This method overcomes the limitations of current methods such as high-speed fluorescent imaging or cell counting, as it accurately assesses device performance in complex, high concentration mixtures. It uniquely takes advantage of pulse processing in flow cytometry to quantify cell separation efficiencies and resulting sample purities, including both single cells and cell clusters. Additionally, it can be combined with cell surface phenotyping to measure separation efficiencies and purities in complex cell mixtures.

Summary: Upconverting stimulated emission depletion microscopy (U-STED) is an effective approach for super-resolution imaging due to its low depletion power and ability to overcome the limitations of the square-root law. However, there is a trade-off between spatial resolution and imaging quality in U-STED, and finding the ideal excitation power is challenging. This study proposes a method to predict the ideal excitation power using non-saturate excitation based on the dynamic cross-relaxation energy transfer of upconversion nanoparticles, allowing for high depletion efficiency and resolution under 40 nm.
